I setup my Windows 2012 RDS box and everything worked well. However, once I published a RemoteApp the RDS server itself went missing from my RDWeb page.
A little annoying, but there is a pretty simple fix (found here)
Basically, share the Remote Desktop Connection program and the edit it and pass in the parameter:
/v: <FQDN of the RDSH server>
mstsc [<connection file>] [/v:<server[:port]>] [/admin] [/f[ullscreen]] [/w:<width>] [/h:<height>] [/public] | [/span] [/edit “connection file”] [/migrate] [/?]
